Abstract
1,270,664. Electro-forming. H. F. MADDOCKS. Dec. 1, 1969 [Aug. 30, 1968], No. 41442/68. Heading C7B. An electro-form e.g. an electro-machining electrode is produced by electro-depositing one or more coatings of metal or alloy e.g. Cu from a Cu pyrophosphate on a mould or mandrel produced from a Zn/Sn alloy having a lower melting point than the coating metal or alloy and removing the mould or mandrell from the coating (s) by immersing the coated mould or mandrel in a liquid e.g. oil having a temperature between the melting points of the coating (s) and mould or mandrel alloy. The electro-form is preferably rotated in the hot liquid and any residue remaining thereon may be eliminated by washing in caustic soda or HCl solution. The Zn/Sn alloy may comprise 92% Sn and 8% Zn, each Œ0À2%, impurities not exceeding 0À05%.
